To @ZZ wle/omit 11m/.y concern,.-

Be it known that I, CHARLES C. CORDRY, a citizen of the United States, residing at Alleghen y, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Spring-Motors; and I do hereby declare the followin gto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same.

My invention relates to weight or spring motors; and it consists in combining with such motor an auxiliary motor for winding up the weights or spring of the main motor, the auxiliary motor comprising in its organi zation a pendulum .whose momentum assists the auxiliary motor in the accomplishing of the purpose desired.

One form in which I 'have contemplated embodying` my invention is shown in the accompanying drawings, and my said invention is disclosed in the following` description and claims.

In the drawings, tion of my device. Fig. 2 shows a'section of the same, taken on line 2 2 of Fig. l. Fig. 3 is a view similar to Fig. 2, but on line 3 3 of Fig. l. Fig. 4 is a horizontal sectional view on line t 4 ofV Fig. l. Fig. 5 shows an enlarged detail of the clutch mechanism, and Fig. 6 shows a vertical section of Fig. 5.

In the figures of the drawings one form of supporting-frame and arrangement of mechanism for carrying outmy invention is shown; but it is obvious that supporting-frames of different forms and differing arrangements of mechanism or gearing could be employed without departing from the .principle of my invention.

The main frame in this instance is composed of a base A and two standards A A2, mounted thereon and suitably connected or braced, so as to firmly hold the parts mounted thereon in position.

Bis the main shaft of the main motor,which is in this instance actuated by weights C C', mountedl on levers cc. On the shaft B are keyed two ratchet-Wheels B', one of which is shown in Fig. 5. At one side of each ratchetwheel is a disk C2, loosely mounted on the shaft, and the levers c c are rigidly connected Figure v1 is a side elevaone or more pawls to 'engageits'ratchet-wheel,

and I propose and prefer to use Ya number of `pawls varying slightly in length'or so placed up'on the disk that .they will engage with the teeth of the ratchet-wheel at slightlyditfer ing points, so that on a reversal of the movement of the lever there will be an instant en. gagement of the ratchet-wheel by one of the said pawls. In this case I show the disk provided with six pawls a, a', a2, 12604, and a5; but a less or greater number may be employed.

D is the power-shaft, which is provided with the fly-wheel d and one or more band-pulleys d' d2, and this power-shaft is connected with the main shaft by a suitable multiplyi ng-gearing, so that the power-shaft is revolved at a high rate of speed, wliile the main shaft moves but slowly.

The weights C C' are so proportioned and given suchla leverage that one of them when its ratchet will operate the power-shaft to doi ,the work desired, and to permit of adjustment 'the weights O C are loosely mounted on the levers and held in the adjusted position by collars c2 c3, secured to the levers by setjscrews.

The weights C C' will be mostetfective when the levers are in the same horizontalplane as the main shaft, andas in operation they move quickly downward out of such position in order to maintain the motor in its most effective operation these levers must be raised and the movement 1epeated. I therefore cause the levers c c' to be raised to bring the weights C C somewhat above the plane of the main shaft and permit them to move downward an equal distance below such plane to cause them to move through the arc' of their greatest efficiency. The raising of the levers is accomplished by the auxiliary motor, which is shown in this instance as a spring-motor operated by the spring E, which has one end secured to the frame and the other to the shaft F. This shaft is so constructed that it may be turned to wind up the spring in a wellknown manner. y

Gis ashaft connected to the main'shaft F by multiplyinggearin g, giving it a much greater Y IOO which is connected by a pitman g' with an arm 7L of an oscillating shaft H. The shaft H extends beyond the main frame and has secured to such extended portion the pendulum I. The shaft H is providedwith an arm 72', which is connected by a pitman j with a crank 7" on the shaft J. The shaft J is provided with the fly-wheel J to insure a uniform rotary motion. On the shaft J is also mounted a crank-disk J2, provided on opposite sides with crank-pins jzjz, each having a frictionroll thereon. These crank-pins are in the path of movement of the levers c c', andwhen such levers have reached the lowest point of their downward movement they are' engaged by said pins and raised to rengage the ratchet and reapply the weight carried thereby to turn the shaft B.

' The pins of the disk are oppositely disposed, so that one of the levers is permitted to descend as the other is being raised.

The operation is as follows: The main motor being connected with the device to be operated, the spring of the auxiliary motor is wound and the pendulum set in motion. The oscillating shaft acts as an escapement, permitting a slow rotation of the shaft G, while the arm h', through the pitman j, imparts movement to the shaft J. One of the levers c c' is at this time in position to turn the shaft B of the main motor, while-the other has its arm engaged by the crank-pin of the crankdisk. The movement of the shaft J causes the crank-pin to raise the other lever until it reaches the highest point of its movement, when it descends and the lever and its weight will act upon the shaft B and continue its movement while the other lever and weight are raised by the auxiliary motor. This operation is continued until the force of the spring of the said auxiliary motor is exhausted, when it must be rewound. The action of the auxiliary motor in raising the weights and levers of the main motor is the same as the rewinding of an ordinary weight-motor. The pendulum acts to give uniformity to the movement of the auxiliary motor and adds thereto its weight and momentum, so that I am enabled to secure the saine results during the whole period in which the auxiliary motor drives the same, and also enables me to operate the main motor by weights which the auxiliary motor alone would be unable to raise.

It will be seen that the main motor may be supplied with one or more levers and weights, though two is the number I prefer and have foundV to give excellent results. It will also be seen that the auxiliary motor may be driven by one or more weights and that the main motor may be a spring-motor instead of weights, as shown, in which latter case the raising of the levers should act to effect an additional winding of the spring sufficient to restore the force expended during its downward movement. It will b e further seen that the weights act with a considerable leverage upon the shaft B, while the auxiliary motor is burdened with only the direct lift of the weights or less, depending upon the position of the weights upon the levers.

What l claim, and desire to secure by Letters Patent, is

l. The combination with a main motojI actuated by a force made operative by being wound up, of a pendulum and means for actuating it, for rewinding the operative force of the main motor, substantially as described.

2. The combination with a weight-actuated motor, of a pendulum and means for actuating it, to lift the Weight to effect a rewinding of said main motor, substantially as described.

3. The combination with a weight-actuated motor having its weight acting by a considerable leverage, of a pendulum and actuating means therefor coacting to raise the weight by a power not in excess of a direct lifting action, substantially as described.

4. The combination with a weight-actuated motor having levers interposed between the weights and the parts moved thereby, of a pendulum and actuating means therefor, for lifting said levers and weights, said pendu- 4 lum acting on the free ends of said levers, substantially as described.

5. The combination with a weight-motor, having levers interposed between the said weight and the parts moved thereby, giving the weights a strong leverage upon said parts, a pawl-and-ratchet construction connecting said levers and the rotary parts of the motor, a pendulum and actuating means therefor, for lifting said weights and levers, substantially as described.

In testimony whereof I affix my signature in the presence of two Witnesses.
